5.12 Adjusting lapped width of upper fabric
For the standard position of the lower knife ① , make the
distance between the lower knife ① tip and the part A of
presser foot to 0.5 ㎜ . (Fig. 5-19)
For the standard position of the upper knife ② , engage
between the upper knife ② and lower knife ① to 0.5 ㎜
when the upper knife ② is at the extreme left. (Fig. 5-20)
The amount of the upper fabric overlap differs depending
on the right-and-left position of the lower knife.
● When the lower knife is moved to the right, the upper
fabric overlap decreases.
● When the lower knife is moved to the left, the upper
fabric overlap increases.
Changing the position of the lower knife ① , the
engagement of the upper knife ② is readjusted to 0.5 ㎜ .

Loosen the screws ③ and ④ to adjust the lower and upper
knives respectively. (Fig. 5-19 and 5-21)
